I demo'ed the G15 at Golftown. I took my current titanium Callaway driver with me to establish a benchmark for comparison purposes. I hit 15 balls with my Callaway and recorded the average carry distance (not carry and roll distance), launch angle and ball speed. I then hit 15 balls with the G15 and recorded the same statistics. My launch angle was about the same with both clubs but my ball speed was increased by 3 mph with the G15 resulting in 9 yards more carry distance. The G15 feels great in the hands, balanced but lets you feel the clubhead. The sound when you hit the ball is is very satisfying, powerful without any wierd harmonics. A crushed it sound. I also demoe'ed the Adams Speedline F11 which did not yield great results and the Taylormade R11 but did not like the feel and sound and the results were not as good as with the G15. This may have been because I was getting tired by then. I ended up buying the G15 and cannot wait to get it out on the course.
